' The present invention 4relates to bus or l'car win- *dowcon'structiong and-more particularly to yan improved arrangement for moving the inside window stop 'toward and away fromfthe window sash, 5 and lfor 'tightly retainingl it inf-its positionfagfains't the Window Y' sash, vto the end lthat -an eiective weather-seal mayrberinantained in the normal closed positionof the sash', and. at thesameftm'e vit Will# be possible through adjustment' of the vand f lowered.

10 Window stop to permit the sash yto be easily raised f .Theinvention is especially intendedviorarail- .road cars equipped with air condition units where y y the window sashes vare normally closed fandwhere 15 it is essential that the car be kept Weatheresealed. 1n' such .cases the passengers have no occasion to raise orlower the sashes, but in the case oan emergency. necessitating the raising of the sash it is desirable that this can be v.easily done by a 20 membero'f the train crew. The invention is intended to accomplish .this purpose. Y f

The adjustment cam device,`according to my invention, comprises a shaft member 33 having a flange head 34 at its outer end, and provided at its inner end with opposed flats 35-4-35 upon@` which the eccentric cam 3B is secured, an aperture 3'! being provided therein through which the iiattened end of the shaft is slipped and The shaft is engaged in y swaged over, as at 38. a .slot 39 in theforward portion 40 of the inside stop, andthe periphery of the cam engages the Aopposed sash engaging'portion 30 andinterme- 4diate' portion 4|, a helical spring 42 being disprosedhupon the shaft'between the cam and the portion'l40 to prevent looseness before assembly Y and during adjustment.

A passage 43 is provided in the shaftv sain is engaged a screw 44 having its head 45 at one end disposed in Va countersink 46 at the 5 outer end ofsaid passage, and having its other Aend extended through an aperture `4'! in the platform strip and screwed into` a threaded bushing 48 swaged intothe base I5 of the fixed stop.` y 'I'he screw head 45 isslotted in the usual mannenand the flanged head34 of the cam `shaft is provided' with slots 494-49 at each side of the counter-sink 46.

ItWill be observed that Whenmthe screw n isV tightened the head 34 of the cam shaft is pressed tightly against the inside stop and the latter is pressed againstthe base of the fixed 4smpwso thatmovement of the inside stop isprevented Inorder to tightly compress the facing materiel i4 toformen effective Weather-Seal, the Sorewi.- is .1,"1ret loosened, and thereupon, the

4cam is turned tobringvitsy enlarged portion toward the sash, ,causing` the inside stop to be m,ovedtoward the sash, `the position being then v ixed 4bv tiehtemine the Screw- When it is. de-

fsiredA to raise the window sash the screw is `loosened and by turning` the cam to move its enlargedportion awavfrom the sash the inside stop'is shiftedinwardly ,away from the facing material I4, as shown in Fig. 4, whereupon the .sash may be` easily raised and lowered.

.. Upon removal of the ,inside stop the spring42 A willfrictionally retain the cam infits adjusted position soy that thisv position vwill not be disturbedunless the same is intentionally manu- .ally changed. l Uponvreplacing the stop the pressure against the side of the sash will `therefore be the` same as the pressurehad prior to the ,removal of the stop, without having to make a` readjustment, of the cam, Y d A convenienttool 50`for operating the device is `shown in Figs. 8 and 9, the edge being cutaway, ,as lat 5|. to` span the screw head 45, and the edge portions at each side beingv adaptedmto engage'` the slots 49 of Ythei cam head.

l 1 In Fig. ,10 I have shown a modification in-vvhich ,doublesashes I0 and` maare provided, Vthe facing material |4 of thefoutersash l0 engaging the-:fixed outside stop flange 9 and the facing materiel Miei. the ilmerseshy ligbengengeged `platform strip 25. and releasingthe sashes is the same as in the e eight inches.

by the portion of the movable inside stop. In this case the base I 5a of the fixed stop is made wider than in the case of the single sash construction, and is provided with a relatively wide recess 24 in which is secured, in addition to the platform strip 25, a second platform strip 25a. The end 21 of the pressure spring 28 of the sash Hl` 'is secured beneath the platform strip 25e, while the end 21e of thepressure leaf spring 28e of the inner sash |02L is secured beneath the The operation of securing rfirst embodiment. Y

While `I have shown only one vcam device in relation to the inside stop it will be understood that in practice a'plurality of them will be provided a't suitable intervals, say of approximately In this way the pressure will be distributed along the edge of the sash.

e' The'invention has been` illustrated as applied .to the vertical sides or posts of the window frame,

but it is obvious that it is not limited to such use l.but may also be incorporated in the top and bottom sides by providing a movable header lpiece and av movable sill, so that tightness at all four sides may be brought about in the same manner, the movable header piece and the mov- `able sill `being substantially the same in construction and operation as the movable inside stop illustrated.

I have illustrated and described preferred and satisfactory embodiments of the invention but it will be obvious that changes may be made therein, within the spirit and scope thereof, as

rdefined in the appended claims.r

Having thus described my invention what I #claim and desire to secure by Letters Patent iszl.
